Police spokeswoman Luba Samri said that initial reports indicated the two rockets landed Thursday in open fields, causing no damage. Authorities said a third apparently was shot down.

Witnesses reported hearing explosions and sirens wailing near the coastal city of Nahariya. Keinan Engel from Nahariya told Israel Radio that he heard the siren follow a loud boom nearby. The Israeli military said it was investigating.

The Israel-Lebanon border has remained very quiet since Israel and Hezbollah guerrillas battled in a monthlong war in 2006. Sporadic incidents of rocket fire have taken place since.

Lebanon's state-run news agency reported three rockets were fired from the village of Housh. There was no immediate claim of responsibility.
